    <p>I am trying to enable <a href="http://nodejs.org/api/net" rel="noreferrer">tcp</a>, <a href="http://nodejs.org/api/http.html" rel="noreferrer">http</a> and <a href="https://github.com/LearnBoost/websocket.io" rel="noreferrer">websocket.io</a> communication on the same port. I started out with the tcp server (part above //// line), it worked. Then I ran the <a href="https://github.com/LearnBoost/websocket.io/blob/master/examples/echo/server.js" rel="noreferrer">echo server example found on websocket.io</a> (part below //// line), it also worked. But when I try to merge them together, tcp doesn't work anymore. </p> <p>SO, is it possible to enable tcp, http and websockets all using the same port? Or do I have to listen on another port for tcp connections?</p> <pre><code>var net = require('net'); var http = require('http'); var wsio = require('websocket.io'); var conn = []; var server = net.createServer(function(client) {//'connection' listener var info = { remote : client.remoteAddress + ':' + client.remotePort }; var i = conn.push(info) - 1; console.log('[conn] ' + conn[i].remote); client.on('end', function() { console.log('[disc] ' + conn[i].remote); }); client.on('data', function(msg) { console.log('[data] ' + conn[i].remote + ' ' + msg.toString()); }); client.write('hello\r\n'); }); server.listen(8080); /////////////////////////////////////////////////////////// var hs = http.createServer(function(req, res) { res.writeHead(200, { 'Content-Type' : 'text/html' }); res.end(['&lt;script&gt;', "var ws = new WebSocket('ws://127.0.0.1:8080');", 'ws.onmessage = function (data) { ws.send(data); };', '&lt;/script&gt;'].join('')); }); hs.listen(server); var ws = wsio.attach(hs); var i = 0, last; ws.on('connection', function(client) { var id = ++i, last console.log('Client %d connected', id); function ping() { client.send('ping!'); if (last) console.log('Latency for client %d: %d ', id, Date.now() - last); last = Date.now(); }; ping(); client.on('message', ping); }); </code></pre>

    1. COHTTP typically runs on top of TCP. What do you mean by HTTP and TCP?

    2. COThat's why I'm in doubt. My server needs to communicate with websockets via browsers and TCP connections via mobile apps. Thus I need both protocols.

    3. COPerhaps you could listen as raw TCP and if you detect HTTP, forward to the other handler manually. Likewise, if you detect WS from the HTTP server (WS starts as HTTP), delegate again.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
